Oclasrv.com redirect removal instructions

What is oclasrv.com?

Identical to primosearch.com, deloton.com, rosetheet.com, and many others, oclasrv.com is a rogue website designed to cause redirects to other dubious websites. Research shows that users often visit oclasrv.com inadvertently - they are redirected by various potentially unwanted programs (PUPs) that typically infiltrate systems without permission. Be aware that, as well as causing redirects, PUPs deliver intrusive ads, gather information, and misuse system resources.

oclasrv.com adware

Following infiltration, potentially unwanted programs randomly open new browser tabs/windows and immediately redirect to oclasrv.com. After visiting this site, users encounter consecutive redirects (usually 2 or 3) to other suspicious websites. There is a high probability that these sites will contain malicious websites. Therefore, redirects to/from oclasrv.com may lead to high-risk computer infections. As mentioned above, PUPs deliver various intrusive ads (coupons, pop-ups, banners, etc.) These ads might also lead to malicious websites and/or even execute scripts that download and install malware. Therefore, clicking them can cause various computer infections. Another downside is information tracking. Potentially unwanted programs commonly record IP addresses, keystrokes, queries entered into search engines, URLs visited, pages viewed, geo-locations, and other information that often includes personal details. This data is shared with third parties - there is a high probability that data tracking will lead to serious privacy issues or even identity theft. Furthermore, potentially unwanted programs often misuse system resources to run various processes (e.g., to mine cryptocurrency) without users' consent. In doing so, potentially unwanted programs significantly diminish system performance. For these reasons, we strongly advise you to uninstall all PUPs without delay.

There are hundreds of potentially unwanted programs, all of which are virtually identical. By offering various "useful features" (e.g., anti-virus/anti-spyware, file conversion, weather forecasts, etc.), potentially unwanted programs attempt to give the impression of legitimacy, however, these programs are designed only to generate revenue for the developers. They deliver no real value for regular users. Potentially unwanted programs cause unwanted redirects (thereby promoting malicious websites, most of which are fake search engines), deliver ads, gather data, and run unwanted processes, thereby posing a direct threat to your privacy and Internet browsing safety.

How did adware install on my computer?

Research shows that some potentially unwanted programs have official download/installation websites, however, in most cases these programs are distributed using a deceptive marketing method called "bundling" and/or the aforementioned intrusive ads. "Bundling" is stealth installation of third party applications with regular software/apps. Developers do not adequately disclose these installations - they conceal "bundled" apps within the "Custom/Advanced" settings or other sections of the download/installation processes. Therefore, rushing these processes and skipping steps (and clicking various advertisements), exposes systems to risk of various infections and compromises users' privacy.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, pay close attention when downloading/installing software and browsing the Internet in general. Select the "Custom/Advanced" settings and carefully analyze each download/installation step to opt-out of all additionally-included programs. Bear in mind that criminals monetize third party downloaders/installers by promoting rogue programs (the "bundling" method). Therefore, we strongly advise you to avoid using such tools. It is also important to note that intrusive ads usually look legitimate, however, they redirect to dubious websites (e.g., gambling, adult dating, survey, etc.) If you experience such ads, immediately eliminate all suspicious applications/browser add-ons.
